The question is whether to go further than that, and if so how much.

In *every* case -- and there are many -- where we've had people
express pain, this would have sufficed.

I see. What about passing this decision to DBA? I mean a GUC can_cancel_session = user, dbowner (default is '' -- only superuser). You can select one or both options. This GUC can only be changed by superuser.
